As before, the OpenVSP Workshop consists of presentations and tutorials by VSP developers and power users. Topics range from introductory to advanced model building, reports on cutting edge development, and work that real users are accomplishing with OpenVSP.

Given the major redesign of Version 3.x.x and the influx of new users, we will focus the first day (8/11) on beginners and those who would like a thorough run through the entire interactive interface and explanation of the parameters. We will also present what we have … Read more

OpenVSP 3.0.4 is mostly a bug fix release. This should fix a bunch of issues with DegenGeom in preparation for things to come. Also fixed are a bunch of problems with 6-series and file airfoil types. Anyone using v3 should certainly update.

Bug fixes in this release include:

Six series leading edge creep

Crash for very thin six series airfoils

Fix problem copy/pasting file airfoils

Update overall wing aspect ratio display

Don’t deselect Geom when executing DegenGeom

Fix sign assumption in z camber of DegenGeom for reflex or inverted foil

OpenVSP 3.0.3 includes a handful of bug fixes and small improvements to the 3.0 series. Versions 3.0.1 and 3.0.2 included quick fixes for urgent last minute bugs — but they did not include a complete release note.

API Users Note:
The calling arguments in four functions were changed: CutXSec, CopyXSec, PasteXSec, and InsertXSec. See Wiki for details.

Version 3.0.0 compared to version 2.3.0 includes too many changes and improvements to list. OpenVSP v3 is a near total re-write that has been three years in the works. Many thanks to the entire core OpenVSP team. This is what you’ve all been waiting for!

Since 2.9.7, version 3.0.0 has a handful of small fixes and features, and one major new feature that has long been in development.

This version includes some nice improvements, but also a bunch of small bug fixes that have been preventing people from getting work done. If you’ve been hitting these, you’ll certainly want to update.

Improvements include:

Issue error when you try to set secondary & primary sweep location equal

This version includes a large number of changes both features and fixes. Some of these fixes took longer than expected — and one of the features is pretty big, so this release took much longer than anticipated. Look for subsequent releases to be smaller and more frequent as the bugs are chased out.

Warning: One bug fix required an incompatible change in how skinning is calculated. If you have used a Fuselage or Stack component with skinning, you will need to adjust your tangent strengths — the geometry will be wrong when you open it. I am very sorry for this inconvenience.

Note: The file extension for custom components has been changed from .as to .vsppart. Similarly, the file extension for scripting has been changed from .as to .vspscr… Read more

The first public alpha release of the v3 re-write of VSP is now available for download. Please take it for a test drive. For real work, please continue using 2.3.0.

For the past two years, a dedicated team has been re-writing VSP from the ground up. The core v3 team responsible for this work so far is: Alex Gary, J.R. Gloudemans, Yue Han, David Marshall, and Rob McDonald.

The v3 effort is a major refactoring and rewriting of VSP. Although it should look/feel mostly the same to casual users, everything is different under the hood. I will write a series of blog posts in the coming weeks on the user-visible changes and how to make the most of them.

The alpha series will be numbered 2.9.X, leading to an eventual production-ready 3.0.0. This alpha release is not for production use. It … Read more

Version 2.3.0 contains one significant feature and a small bug fix. Version 2.3.0 is likely the last 2.X feature release for VSP. We will continue making 2.3.Y bug fix releases for a long time.

For some time, almost all developer effort has been focused on the pending 3.X project. VSP v3 is a near total rewrite keeping everything you love about VSP, but ushering in new features galore and a more maintainable code base. We hope to release a not-for-production-use alpha version of v3 for users to begin testing soon.

Fixes/features in this release:

Add ability to model outer domain boundary in CFD Mesh.

Match multi-body edge shares in CFD Mesh. (Thanks Sriram R.)

You can now generate a CFD Mesh including the outer boundary. Some volume grid generators need to start with a full… Read more
